Selected work

Six builds, no filler.

Every project here was built with AI as my main tool. The screenshots and clips come from the real builds.

Monster Merge

Hatch eggs, merge monsters, chase rare mutations. I built the systems, the monsters and the polish with AI in Roblox Studio, and backed every phase with automated tests and live checks.

Four mutation looks, made by one shared rule for every species. Tap one.

57/57server tests passing: merge rules, request security, economy, simulated saves

40variants of the 10 original species (4 looks each), all passing a placement test

≤1.3σlive mutation counts stayed within 1.3 standard deviations of the set odds over 200,000 rolls

Server decides. A merge starts the moment you drop, but only the server's answer decides what appears.
Balanced by simulation. Luck upgrades were priced with 12 simulated 8-hour sessions on the game's real config.
Frost Titan: 125 parts, 10 joints and a 38.4 s idle loop, built in Studio to match the design part for part.

In Roblox Studio

Normal, Golden, Cosmic and Shiny Frost Titans on a player's board — **On the board.** Normal, Golden, Cosmic and Shiny Frost Titans, with a Cosmic Titan for scale.

Two Frost Titans in different idle poses — **Idle poses.** Each titan starts at its own point of the loop, so a row never moves in step.

Close-up of the Frost Titan's head and glowing chest crystal — **Close-up.** Brow, eye slits and the pulsing frost heart.

A full board of ten Frost Titans — **A full board.** Ten titans, ten different points in the same 38.4 s loop.

Frost Titan standing in the game world — **In the world.** The low-poly map around the player plots.

Index cards: tier 10 undiscovered and the Frost Titan — **Index.** Undiscovered tiers stay a silhouette until you merge them.

FERNECHO

My “What if…?” channel on TikTok. Every episode comes out of a canvas renderer I build with AI: the voice-over goes in, a finished vertical video comes out. No stock footage and no AI images: the scenes are drawn in code.

1080 × 1920 · 60 fps 0 stock clips scenes synced to voice

ScriptHook in the first two seconds, then the scenario escalates step by step.

AI voiceOne fixed narrator voice from Google AI Studio, the only manual step.

Scene syncThe renderer finds the paragraphs by the pauses in the audio and pins each scene to its paragraph.

Export1080 × 1920 at 60 fps, captions burned in, and the end flows back into the start.

The clips on this page are rendered with English captions. The channel itself posts in German.

RobloxCompetitive FPSIn development

REFLEX

A competitive shooter with no guns: you fire from your hand. Charged shots, dash, slide and ultimates, with ranked play and mostly cosmetic monetization, so it never turns pay-to-win. Its arena, Cirrus, is in greybox with a mirrored layout, so both teams start even.

How I prompt

Great output starts with a great brief.

AI is only as precise as the instructions it gets. This is the structure behind every project on this page, shown on the brief for the Frost Titan.

GOALDesign the new final-tier monster for Monster Merge: the Frost Titan, Tier 11, Secret.

CONTEXTIt merges from two Cosmic Titans. Players mostly see it small, from the board camera, on an 8-stud cell.

CONSTRAINTSFootprint under 7.8 studs, height under 10. SmoothPlastic like every monster, Neon only for eyes and heart. Mutations never recolour the eyes.

REFERENCEIt has to read as part of the same low-poly family as the other ten species.

OUTPUTTurnaround views, palette, a rig with joints and a seamless idle loop. Then build it in Studio.

PROOFShow it still reads at 72 px, stands on its tile in all four looks and matches the blockout part for part.

GoalOne sentence that says exactly what you want. A vague goal gets you a generic result.

Numbers over adjectives“Under 10 studs” beats “not too big”. Measurable beats vague.

Phases, not one shotDesign, then core loop, then polish. I review every phase before the next.

Make it prove itTests, logs, screenshots, 200,000 test rolls. Claims need evidence.

Ask what wasn't testedEvery report lists what could not be checked yet, so the blind spots are known.

Humans decideStyle, scope and what ships stay my call. AI does the heavy lifting.
